sophia rolls a six-sided number cube labeled from 1 to 6. what is the probability that she rolls a number greater that 4 or a 2?

The probability that she rolls a number greater that 4 or a 2 = or 50%

Step-by-step explanation:

Given:

A six sided number cube is rolled labelled from 1 to 6.

To find the probability that she rolls a number that is greater than 4 or a 2.

Solution:

The possible outcomes of rolling a six-sided cube are:

{1,2,3,4,5,6}

Event A:

The favorable outcomes greater than 4 are:

{5,6}

Probability of event  A to occur =

Event B:

The favorable outcome is a 2

{2}

Probability of event  B to occur =

We find that the two events are mutually exclusive as they have no common outcomes.

Thus, the probability that event A or B occurs ( P(AUB) ) can be given as:

⇒

Since denominators same, so we add the numerators.

⇒

Reducing it to simpler fraction:

⇒     (Answer)

Thus, the probability that she rolls a number greater that 4 or a 2 = or 50%

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
